We want to get an idea of how many tickets we have and what our issues are. Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.

Figure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT. Show all your working.(c) Implement your design using AND/OR/NOT logic gates and risingedgetriggered D-type Flip Flops. Your answer should include a circuitschematic.

A controller is required for a home security alarm, providing the followingfunctionality. The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…
